Abstract: The invention basically includes a movable base which contains a plurality of hyperbolic mirror reflectors having their axis directed upwardly towards an absorber plate and which is directed upon an energy converting unit. The solar energy is absorbed by the unit and is used to heat a gas such as air which is circulated through the unit, with the heat being subsequently stored in a heat absorbing particulate material such as lava rock or the like. Additionally, the movable platform is controlled by a gravity drive (for very low power consumption during operation) and which is in turn controlled by a photoelectric solar detector mechanism. The detector mechanism is so designed that it receives the early rays of light of the sun and signals the control system to commence tracking the sun.
